In a process unique to the mining industry, mineral ore must be extracted and conveyed to a means of transportation in a challenging environment. This involves the use of high-power fixed and mobile equipment with complex kinematics. The entire process is carried out in cyclic and variable operating conditions with significant safety and accessibility constraints. Mining operations are also a source of noise and vibration pollution both for site workers and people in the surrounding area.

Traditional Field Pass-by measurements are still the only way to certify a vehicle for exterior noise emission during operation, but Indoor Pass-by provides an extremely powerful and repeatable method of troubleshooting exterior vehicle noise in the controlled environment ofan anechoic chamber.

Industrial noise generated from plants, mills, refineries, shipping docks, utilities, and more, impact the quality of the surrounding community. By controlling and monitoring this noise a community and industry can establish a working relationship that will benefit all. An effective noise monitoring program will allow an industrial site to understand the noise sources and time periods that are causing concerns and then develop a plan for mitigation.

As a major source of renewable energy, wind turbines are continuing to experience exponential growth, with a production capacity that is doubling every three years. Reliability and the optimisation of maintenance have become major economic challenges for wind turbine operators.

The paper industry depends upon a continuous industrial process in which the paper machine is the central factor. This system is based on several variable speed rollers mounted on roller-bearing blocks, and damage to a single block can be enough to shut down production for several hours.

As of April 2008 the entertainment industry is now expected to comply with ‘The Control of Noise at Work Regulations’. Owners and venue operators are now legally obliged to ensure their workforce is protected from excessive noise levels. To help you understand the key issues, Pulsar Instruments Plc have produced a Free Information Pack detailing the new regulations and offering simple advice and answers to the most commonly asked questions.

Workplace noise monitoring is an interesting subject that can appear complex, but it is always worth remembering what you are trying to achieve. This can be summarised as: ““Minimising or avoiding the risk of noise-induced hearing loss in the workplace to comply with local, noise-based, legislation”” Such legislation is usually based on a European Directive that is then modified to suit the needs of each particular country. For example, in the United Kingdom, the ‘The Control of Noise at Work Regulations 2005’ are based on the European Union Directive 2003/10/EC; usually called “The physical agents (noise)” directive and expanded upon by the Health & Safety Executive.

In a world where there is a drive for everything to be quieter, vehicle noise measurement and control is a growing application. If measurements need to be made to ISO 5130:2007, which is an internationally recognised standard for vehicle exhaust noise testing, a more detailed measurement needs to be made. ISO 5130:2007 requires three consecutive measurements to ensure repeatability. These measurements are taken at a specified engine speed, or RPM, and the maximum sound level produced during the test is taken.

With today`s growing focus on noise control issues and the emergence of sound quality as an important aspect of product design, acoustic material testing is becoming increasingly relevant to engineers, designers and manufacturers from a broad range of industries. Acoustic material testing is the process by which the acoustic characteristics of materials are determined in terms of absorption, reflection, impedance, and admittance, including transmission loss.

Vibration testing is is used for aerospace and defence testing, ground transportation, transport simulation, package testing, altitude simulation and more. Our comprehensive range of LDS electrodynamic shakersare designed for vibration testing of devices of any size - from a semiconductor component to a complete satellite system, to see how it will stand up to real-world conditions. With an LDS vibration test system your shaker, power amplifier, vibration controller and even environmental chamber are not only controlled from one PC, they run under one software package. Combined with data acquisition systems and analysis software suites, Brüel & Kjær ofers the complete vibration testing solution to establish proof of quality according to national and international standards, such as DIN, ISO, BS, MIL, IEC and ASTM.

Environmental noise monitors that connect directly to process measurement and control systems. Many industrial plants have a variety of process sensors strategically placed around their site so that safety, environmental impact and efficiency can be monitored and managed, in real time, from one or more control rooms.

Cirrus Environmental has been providing noise monitoring systems for motorsport noise measurement and control for a number of years and has supplied systems to some of the leading circuits around the world. Combining noise monitors with the NoiseHub software, we can provide a tailored package to meet your needs.

By implementing a noise and vibration monitoring system, the impact of construction site activities can be managed by: Complying with legal requirements relating to public health sanctioning the absence of appropriate precautions to limit abnormally high levels of noise and vibrations. Taking environmental quality considerations into account (HQE approach). Limiting noise and vibration pollution with the comfort of neighbouring residents in mind. Enabling companies in the public works and construction industry to adopt a transparent approach to communication with local residents, in order to avoid resistance and instead gain their support for a given project. Providing the site manager with reliable and official data, should it be required. 01dB offers solutions for construction professionals to suit the requirements of each building site. It provides them with metrological systems (such as the certified DUO sound level meter, dB4 and MR2002) with 01dB WebMonitoring services to ensure optimal control of noise & vibration impact of the construction work, using as well communication tools intended for the general public.

Efficiency, performance, reliability and effectiveness; these are qualities that we know professionals in the logistics and packaging industries want from their on-site baler.

HSM can supply customers with a wide range of balers from our comprehensive range of models; we pride ourselves on using our experience to find the best solution, every time. Our balers have touch-screen control panels, are operationally efficient, simple to maintain and offer an excellent return on investment.

Energy efficiency is of the utmost importance to HSM and we know that our German-designed, manufactured and tested balers exceed all operational and safety standards and offer an environmentally-sound method of waste removal.

Our new generation of modern balers have been created to use low levels of energy, generate a minimum level of noise and operate without the need for constant supervision.

Considerations for sound abatement abound within certain industrial facilities. The new OSHA compliance mandates require noise control for employees and visitors to these facilities who may be exposed to continuous influences of high sound levels and reverberation properties, due to activities within these facilities. Troy Acoustics™ provides the Troy System™ materials and design solutions, which have been proven to minimize the effects of these objectionable sound levels and their effects, to insure compliance with current OSHA standards.
